    About CERRE

    Providing top quality studies and dissemination activities, the Centre on Regulation in Europe

    (CERRE) promotes robust and consistent regulation in Europe’s network and digital industries.

    CERRE’s members are regulatory authorities and operators in those industries as well as

    universities.

    CERRE’s added value is based on:

    • its original, multidisciplinary and cross-sector approach; • the widely acknowledged academic credentials and policy experience of its team and

    associated staff members;

    • its scientific independence and impartiality; • the direct relevance and timeliness of its contributions to the policy and regulatory

    development process applicable to network industries and the markets for their

    services.

    CERRE's activities include contributions to the development of norms, standards and policy

    recommendations related to the regulation of service providers, to the specification of market

    rules and to improvements in the management of infrastructure in a changing political,

    economic, technological and social environment. CERRE’s work also aims at clarifying the

    respective roles of market operators, governments and regulatory authorities, as well as at

    strengthening the expertise of the latter, since in many Member States, regulators are part of a

    relatively recent profession.

    The project, within the framework of which this report has been prepared, has received the

    financial support of a number of CERRE members. As provided for in the association's by-laws, it

    Executive Summary

    Historical regularity suggests that approximately every 10 years a new generation of mobile

    communications technology is introduced. The next generation – 5G – is expected to be

    introduced around 2020. Each new generation represents a complex interplay between

    interdependent stakeholders, including infrastructure equipment manufacturers, device makers,

    operators, and end-users, as well as regulators and policy makers at national, regional and

    global level. This is a high-stakes game requiring deep investments which can only be successful

    if well coordinated, and when supply and demand can be aligned.

    European policy makers have a keen interest in the success of the next generation because

    ubiquitous and high capacity electronic communication infrastructure is recognised as a

    cornerstone of economic development and productivity growth. The second generation, GSM,

    was a big success. It reached its peak in deployment in 2015 with 3.83 billion subscribers served

    through over 700 operators in 219 countries and territories.

    With 5G rapidly shaping up in the R&D and standardisation environment, what are the lessons

    to be learned from 1G through 4G that should be taken into account to ensure a successful

    development and deployment of 5G in Europe? What does 5G have in common with previous

    generations and where is it different? What are the implications? Moreover, is the path towards

    the future predetermined by the previous generations, by a prevailing industry structure, or are

    there alternative routes? Is there possibly a fork in the road ahead that requires special

    attention from policy makers and regulators, as it may lead to different futures? When there are

    different futures with different outcomes, is one more desirable than the other? In sum, what

    would be the policy and regulatory framework required to enable the success of 5G in Europe?

    To respond to these questions, this report identifies first, on the basis of an assessment of the

    previous generations of mobile communication technologies and against the backdrop of

    European leadership in the development and deployment of GSM, the policy and regulatory

    lessons to be drawn from the latter’s success.

    Secondly, it provides a description of 5G, the performance objectives that have been assigned

    to it, the latter’s architecture and key features; the report then compares those features with

    previous generations.

    Thirdly, it describes two stylised, extreme images of possible futures of 5G, ‘Evolution’ and

    ‘Revolution’. Those images represent two different sets of outcomes that are enabled by two

    different sets of policies and regulatory interventions. They constitute a fork in the road that

    policy makers and regulators will have to navigate in the years to come.

    It should be emphasised that the latter do not aim to represent the complexity of how the

    actual future may unfold, nor should they be considered as scenarios, such as those initiated by

  • 170330_CERRE_5GReport_Final 8/116

    Shell in the eighties. They are merely intended to stimulate the debate on the policy and

    regulatory conditions for the successful deployment of 5G in Europe.

    Fourthly, the report describes the policy and regulatory framework that would be required to

    enable each of these images.

    ‘Evolution’ follows the pattern of previous generations and current trends. ‘Revolution’

    represents a clear break with these trends. It exploits the opportunities of standardised

    application programming interfaces (APIs) for service creation, being enabled by network

    virtualisation as an architectural foundation of 5G. These open APIs allow the market entry of a

    multitude of virtual mobile network operators (VMNOs). VMNOs are dedicated to serve

    particular industry verticals or economic sectors with tailored feature sets and tailored qualities

    of services.

    In ‘Evolution’, the regularities and trends that can be observed from the previous generations of

    mobile communication, i.e. 1G through 4G, are considered as the main determinants of the 5G

    future. A key assumption in this image is that the core business of the mobile operators

    continues to be serving the mass market of consumers.

    ‘Revolution’ reflects the shift to a layered model with multiple specialised providers at each

    layer. At the lower layer are the passive infrastructure facilities providers. At the next layer up

    are the network operators – the owners of radio frequency licenses and of active infrastructure

    facilities. These mobile network operators are the wholesale providers of a range of connectivity

    services with various grades of quality to the virtual mobile network operators (VMNOs) at the

    top layer.

    These VMNOs can be compared to the MVNOs of earlier generations, serving specific market

    segments and leveraging a particular brand. However, they are different as VMNOs have full

    control of a virtual slice of the network infrastructure to deliver services with differentiated

    quality levels. In ‘Revolution’, the number of VMNOs is very large. In principle, each firm that

    wishes to extend its reach to end-users through a mobile service can do so as a VMNO using its

    own brand and applying bundling with other business services. As firms compete for end-users,

    they are expected to compete for providing the best virtual mobile services as well. This results

    in a very dynamic wholesale market. This is a market that unlocks a higher willingness to pay,

    which, through differentiation of network services, will flow through to incentivise 5G network

    investments.

    The policy and regulatory actions that enable ‘Evolution’ build on the new Electronic

    Communications Code and the 5G Action Plan. They are also related to the topics of, amongst

    others, trading in radio spectrum usage rights, coverage obligations, indoor access, network

    sharing, net neutrality and minimum requirements for public protection and disaster relief.

    The policy and regulatory actions that enable ‘Revolution’ also build on the new Electronic

    Communications Code and the 5G Action Plan. However, they also involve a 5G Action Plan

    focused on the European-wide use of open APIs. The transition to the new industry

  • 170330_CERRE_5GReport_Final 9/116

    configuration is recognised as a major innovation project requiring restraint in terms of

    regulation. Regulatory action is based on intervention only in case of market failure, e.g. in areas

    such as retail market access, open and common APIs and national roaming. Special action is

    required for net neutrality, liberalisation of SIM usage and use of multiple VMNOs on a single

    device.

    1 Introduction

    Historical regularity suggests that approximately every 10 years a new generation of mobile

    communications technology is introduced. The sequence started with 1G in 1981 and the latest

    generation, 4G, was introduced in 2009. Hence, the next generation – 5G – is expected to be

    introduced around 2020. Each new generation represents a complex interplay between

    interdependent stakeholders, including infrastructure equipment manufacturers, device makers,

    operators, and end-users, as well as regulators and policy makers at national, regional and

    global level. The interplay concerns the allocation and assignment of new radio frequency

    bands, the development of a new standard, the development of new network equipment, the

    investment in new infrastructure build-out, the launch of new devices and the uptake by end-

    users. This is a high-stakes game requiring deep investments which can only be successful if

    well-coordinated, and when supply and demand can be aligned.

    European policy makers have a keen interest in the success of the next generation because

    ubiquitous and high-capacity electronic communication infrastructure is recognised as a

    cornerstone of economic development and productivity growth. Moreover, at the European

    level, electronic communications has become a strategic element in the creation of the single

    internal market. Following the success of the second generation – GSM – the question of

    European leadership in the development and deployment of cellular communications is being

    raised with each successive generation.

    The benchmark for European leadership in mobile communications is GSM, a second generation

    technology introduced in 1991, which reached its peak in deployment in 2015 with 3.83 billion

    subscribers served through over 700 operators in 219 countries and territories. This is

    phenomenal achievement, especially when recognising that the nearest competing 2G

    technology – CDMA – reached its peak with 374 million subscribers also in 2015. This represents

    a factor 10 difference. However, in Europe the next generation 3G – UMTS is generally

    considered as less successful, having had a slow start in deployment compared to a much faster

    uptake of 3G in the USA and Asia. Nonetheless, from a consumer welfare perspective, 3G and

    4G can be considered as quite successful, considering the price levels and the data rates

    provided.

    Therefore, with 5G rapidly shaping up in the R&D and standardisation environment, what are

    the lessons to be learned from 1G through 4G that should be taken into account with the

    introduction of 5G in Europe? What are the policy and regulatory lessons to be applied for a

    successful deployment of 5G in Europe? What does 5G have in common with previous

    generations and where is it different? What are the implications? Moreover, is the path towards

    the future predetermined by the previous generations, by a prevailing industry structure, or are

    there alternatives routes? Is there possibly a fork in the road ahead that requires special

  • 170330_CERRE_5GReport_Final 12/116

    attention from policy makers and regulators, as it may lead to different futures?1 When there

    are different futures with different outcomes, is one future more desirable than the other?

    To respond to these questions, this research report provides first an assessment of the previous

    generations of mobile communication technologies and derives the policy and regulatory

    lessons against the backdrop of European leadership in GSM. Secondly, it provides a description

    of 5G, the performance objectives that have been set, its architecture and key features and

    compares this with previous generations. Thirdly, it describes two possible stylised images for

    the future of 5G, an ‘evolution’ image and a ‘revolution’ image. These two images represent two

    extremes to capture the widest range of possible 5G futures. These images are deliberately

    chosen to represent extremes, as it is not the intention to try to predict the most likely future of

    5G. Furthermore, these images of the future do not aim to represent the complexity of how the

    actual future may unfold, nor should they be considered as scenarios, such as those initiated by

    Shell in the eighties. They are aimed at stimulating the debate on the best set of policy and

    regulatory conditions for the successful development and deployment of 5G in Europe.

    The ‘evolution’ image follows the pattern of previous generations and current trends. The

    ‘revolution’ image represents a clear break with the trends as it exploits the opportunities of

    open access APIs being enabled by network virtualisation as an architectural foundation of 5G.

    These open APIs allow the market entry of a multitude of virtual mobile network operators.

    VMNOs dedicated to serve particular industry verticals or economic sectors with tailored feature

    sets and tailored qualities of services. These VMNOs may originate from the industries they

    serve, such as internal ICT departments extending their reach to customers, from services firms

    specialised in and dedicated to a particular industry, from incumbent2 operators diversifying

    beyond the mass market of consumers and from start-ups.

    These two stylised images reflect two different futures of 5G, two extremes. They yield two

    different sets of outcomes that are enabled by two different sets of policies and regulatory

    interventions. They constitute a fork in the road that policy makers and regulators will have to

    navigate in 2017.

    This research report is structured as follows: in Section 2 the European leadership role in mobile

    communications is explored. It also derives the regularities across the subsequent generations

    1G through 4G and provides an interpretation in the light of the next generation, i.e. 5G. Section

    3 describes the architecture and features of 5G, with special attention to virtualisation. The

    demand side expectations are also captured in this section. Section 4 introduces the two stylised

    images of the future of 5G. Section 5 describes the ‘Evolution’ image using the Porter/Wheelen

    industry structure dimensions and includes a sketch of the anticipated industry outcome. This

    outcome is compared with the GSM success factors identified in Section 2. In Section 6, the

    period as referenced. The term does not typically include mobile virtual network operators.

    policy and regulatory actions are derived that would enable the ‘Evolution’ image. Section 7

    describes the ‘Revolution’ image and the anticipated outcome, while Section 8 captures the

    policy and regulatory actions that would be required to enable the image. Section 9 provides as

    a summary an overview of the pros and cons of the two stylised images. As background

    information, Annex A provides a short brief on the characteristics of the mobile communications

    business. Annex B provides the list of abbreviations and acronyms. Annex C presents a timeline

    of major developments in mobile communications. Annex D explores the 5G related radio

    frequency management challenges and Annex E addresses net neutrality in the context of

    managed services.

    2 The leadership role

    In describing the European leadership in mobile communications typically, reference is made to

    the global success of GSM, a second generation technology introduced in 1991, which reached

    its peak in deployment in 2015 with 3.83 billion subscribers through over 700 operators in 219

    countries and territories. This is phenomenal achievement, especially when recognising that the

    nearest competing technology – CDMA – reached its peak at 374 million subscribers also in

    2015. This represents a factor 10 difference.

    However, the next generation 3G – UMTS – is generally being considered as less successful,

    having had a slow start in deployment compared to a much more rapid uptake in the USA and

    Asia. Nonetheless, from a consumer welfare perspective, 3G can be considered as quite

    successful, considering the price levels and the additional functionality provided.

    For an appreciation of the differences a comparison is made between 2G and 3G based on the

    ‘roadmap to market’ and the ‘leadership role’ as identified for GSM by Hillebrand3 (see Table 1

    and Table 2 below).

    As Ungerer observed,4 the deployment of GSM and DCS1800 systems in Europe was unique

    because it coincided with the de-monopolisation and introduction of competition in mobile

    communications. The early accelerated mass deployment of GSM was mainly due to new

    entrants. At the end of 1993, digital was accounting for only 9% of mobile terminals and new

    entrant Mannesmann D2 in Germany accounted for 46% of the European GSM market. With the

    competitive pressure from Mannesmann on Deutsche Telecom, the German market

    represented 79% of the digital market in Europe.

  • 170330_CERRE_5GReport_Final 17/116

    From 1993 to 1996, a number of procedures were undertaken under EU competition law to

    force fair terms for new entrants in several countries, including Italy, Spain and Ireland. This

    culminated in the Mobile competition directive issued in 1996, which also mandated the issuing

    of the DCS1800 licenses with the deadline of 1 January 1998 – coinciding with the date on which

    the European telecommunications market was to be liberalised.

    In 1998 there was a debate in the Commission on whether the licensing of 3G should again be

    mandated under competition law or under the sector-specific internal market regulation.

    Competition law would have given a much more direct enforcement role to the Commission in

    overviewing and coordinating licensing and auctions. In the end, the decision was taken in

    favour of the internal market approach on which the electronic communications regulatory

    framework is based.

    With 3G auctions construed to maximise proceeds for the national budget and the auctions

    coinciding with the Internet bubble, meant that investment resources were mainly spent on

    licenses. New entrants were no longer the main drivers and deployment was mainly with

    incumbents and GSM entrants of the nineties. All spent large amounts on the 3G licenses to

    secure their 2G position, not for the rapid deployment of 3G. All of this led to a slow deployment

    and the loss of the European position in digital mobile.

    It should also be noted that the context has changed significantly between the launch of 2G and

    the launch of 3G, and further into the 4G era: (1) the market has been fully liberalised and has

    become highly competitive; (2) the position of European equipment manufacturers and mobile

    operators has changed as the industry has become global; (3) the role of nation states has

    changed as part of the liberalisation process and as part of the European Union project; (4) 2G

    was instrumental in establishing the mass consumer market, while 3G and 4G are largely

    representing replacement markets for voice and enhancement markets for data; and (5) the role

    of the device market has become much more important, the choice of smartphone and related

    applications platform have become leading in the decision making process of consumers.

    As Fejióo et al. pointed out, during the earlier mobile generations a ‘virtuous circle’ of

    investment, innovation and adoption of services had been in play. With the introduction of 4G,

    this cycle appears to be broken, being replaced by a cycle that runs in the opposite direction.

    Now, the innovation and adoption of services require investments from mobile operators

    although these will not necessarily lead to an increase in operators’ revenues.5

    Hence, actions that were identified as having been crucial to the leadership role in GSM have to

    be reinterpreted in the current context of 5G.

    2.1 Regularities in next generation mobile communication: 1G

    through 4G

    Notwithstanding the differences between the generations, many actions are part of a recurring

    pattern, a pattern typical for the introduction of a new generation of mobile technology. For

    Europe, these events and actions – generally called attributes – have been captured in Table 3

    for the generations 1G through 4G. The column 5G has been added to capture those attributes

    as they could be observed to date.6

    It should be noted that GSM not only represented a major growth phenomenon, it also

    established the foundational elements in the cellular communications business that are still valid

    today in Europe, such as calling party pays, international roaming and mutual recognition of

    terminal devices. In Table 3, these have been denoted as ‘established routine’ (est. rout.).

    2.2 Interpretation of the regularities and trends leading to 5G

    The four subsequent generations of mobile network technology show a clear pattern in terms of

    succession: every 10 years, a new generation is introduced.10 The developments to date with

    respect to 5G are at large aligned with these regularities. Hence, we may expect 5G to be

    introduced around 2020.

    The initiative for a next generation typically emerges at the time a previous generation is being

    introduced in the field, i.e. some 11-10 years before the launch date. In 1G and 2G these

    initiatives originated with the mobile operators, at that time the government-owned national

    telecom monopolies. These initiative included R&D into the next generation by the incumbent

    players. With the introduction of competition, starting with the deployment of 2G and being

    fully established when 3G was introduced, the emphasis had shifted to pre-competitive R&D

    programs initiated and sponsored by the European Union with participation of equipment

    manufacturers, operators and academic research centres. During the 3G era, the operators

    typically reoriented their R&D activities towards service provision, while leaving network-related

    R&D to the equipment vendors. The 5G-oriented research within the EU funded FP7 and Horizon

    2020 programs aligns with this trend, in terms of timing, content and industry participation. The

    strategic collaboration agreements on 5G R&D made by the EU with Japan, Korea, China and

    Brazil are consistent with 5G to become a global standard, with 3GPP as the standardisation

    platform. A platform that was established based on European initiative recognising the extended

    geographical scope of the standardisation efforts, largely as a result of the global deployment of

    GSM.

    At the time of a next generation initiative, the allocation of new frequencies is also made by the

    CEPT, in line with agreements made at the global level within ITU-R.11 For the first three

    generations, new radio frequency bands were typically found at higher frequencies, which

    provided for higher data rates. This nicely coincided with the need for increasing data rates per

    user. With increasing mobile use, the pressure for more spectrum mounted and through the

    transition from analogue to digital broadcasting, lower frequency bands were becoming

    available, e.g. the 800 MHz band as part of 4G. The plans for 5G are in line with this trend, i.e.,

    high-end extensions are foreseen in bands between 24 GHz and 83 GHz,12 as well as a low-end

    re-allocation of the 700 MHz band.13

    However, the linkage between next generation and new spectrum assignments appears to have

    become weaker. On the one hand, auctions are organised at the national level as and when new

    10 Note that 4G – LTE was ahead of ‘schedule’ with close to 2 years, apparently to stay ahead of WiMAX, which had

    become an IMT2000 family member. 11

    At certain instances the ITU-R has been leading, at other times the CEPT proposed an allocation scheme to the

    WRC. 12

    See for details https://www.itu.int/dms_pub/itu-r/oth/0c/0a/R0C0A00000C0014PDFE.pdf 13

    In a number of countries the 700 MHz band is made available earlier for use by LTE. See also Annex D.

  • 170330_CERRE_5GReport_Final 23/116

    or re-allocated spectrum becomes available and, on the other hand, spectrum is now assigned

    on a technology-neutral basis, i.e. next generation equipment may be deployed in bands

    originally assigned for previous generations.14 This trend started with 4G and also applies to 5G.

    The prominent coordinating role of operators in the introduction of 2G, in terms of timing and

    functionality, has moved to the background in 3G and 4G. On the one hand, the competitive

    market is expected to drive the introduction process – and coordination could be interpreted as

    collusion – and, on the other hand, the operational aspects of a next generation are now

    addressed by the GSMA, the institutional successor of the Memorandum of Understanding

    between operators in the 2G era.

    At the time of 1G and 2G, the introduction of a new generation required deep investments in

    the roll-out of new infrastructure replacing the previous generation. With the deployment of a

    packet-overlay network in the form of GPRS, an inter-generational upgrade was introduced:

    2.5G. With 3G, the investment in a new radio access and new core equipment became

    separated in time: first, a new radio was introduced (Wide band CDMA), which was made

    interoperable with the existing 2G circuit switching and 2.5G packet switching core. As part of

    3.5G the packet capabilities were upgraded towards HSPA. In 4G, the circuit core was

    abandoned and the packet core was further enhanced. Still in 4G, a new modulation technique

    was applied on the radio access (OFDMA), requiring upgrades of base stations and handsets,

    while earlier generations remained backward compatible with existing evolved core network.

    LTE-Advanced, which is providing higher data rates based on carrier aggregation, represents the

    inter-generational upgrade to 4.5G. The envisioned evolution towards 5G includes adding a new

    radio access in the frequency bands above 24 GHz to be compatible with the existing evolved

    packet core (EPC). The plans also project the introduction of virtualisation (Software Defined

    Networks and Network Function Virtualisation), which means a further move of functionality

    into software and the application of bulk-standard Ethernet switches and computing resources.

    This is expected to be a gradual process, starting with new interfaces being added to existing

    network equipment.

    Evolution of handsets

    The replacement model of 1G by 2G implied the need for new devices. With the allocation of

    additional GSM bands (1800 and 1900 MHz), followed the introduction of multiband radios

    allowing for interoperability within a single generation across multiple frequency bands. With

    more bands being allocated and assigned over time, the support of multiple bands by handset

    providers in line with the national band plans has become a critical issue. Handset roll-out plans

    14 While spectrum bands may have been made technology neutral some aspects, such as the channel width, may have

    to be aligned with a particular generation of technology. This may involve adaptation of regulatory conditions.

    vendors.15 Furthermore, handset functionality extends well beyond mobile network

    functionality and the launch of new devices is increasingly driven by smartphone vendors, with

    typically a new release every 1-2 years.16 In certain markets, the 3.5 GHz band has been assigned

    but has remained unused, lacking appropriate terminal devices.17 Also, the use of carrier

    aggregation as part of 4G is subject to terminal-network compatibility. In the evolution towards

    5G, this is expected to remain an issue of concern, suggesting the necessity for further

    coordination of frequency plans by national administrations.

    Evolution of the core network based on standards

    Over the generations, the scope of mobile communication standards has evolved from being

    national, through being regional to becoming global. That process has been strongly influenced

    by the regional and subsequently global success of GSM. With GSM deployed in all regions, it

    brought together the interests of operators across the globe in relation to the next generation

    standard to be deployed. With 3G being designed to be compatible with the previous

    generations, three regional standards resulted. 4G in casu LTE and LTE-Advanced have been

    conceived as global standards and are now accepted and deployed as such. 5G will become the

    next global standard for mobile communications. Based on its experience with 3G and 4G, the

    3GPP as standard development organisation is set to create the 5G specifications.

    Evolution towards verticals

    While oriented towards the mass market of consumers, GSM has evolved to support a first

    public sector vertical market: GSM-R serving European railway operators, for which a separate

    frequency band had been allocated in Europe. The GSM-R functionality has become part of the

    general GSM specification, such that the functionality was available to address other similar

    niche markets. A second public sector vertical is being accommodated as part of 4G release 13

    through 15: the public protection and disaster relief (PPDR) sector, which includes the police,

    fire brigade and ambulance services. In Europe, the PPDR sector was previously served through

    a dedicated system called TETRA, operating in a dedicated band. The sector has concluded that

    for the transition from narrowband to broadband it will have to rely on LTE and LTE-Advanced,

    as a dedicated broadband system is not a viable option.

    15 This has for instance led to the Apple iPhone 5 at release not being compatible with the assigned 4G frequencies in

    Belgium. Source: Van der Wee, Verbrugge & Laroy (2015). 16

    3 5G architecture and features18

    5G represents a next step in the technological evolution of mobile communications networks:

    1G was dedicated to telephony. 2G started as capacity expansion for telephony, to which a

    packet-switched overlay network (GPRS) was later added to provide access to the Internet. 3G

    was designed for voice and high-speed data communication (implemented through resp. circuit

    switching and packet switching). High demand for Internet access accelerated the transition to

    the next generation of mobile technology – 4G – also known as Long-Term Evolution (LTE),

    which is packet-switched only.19 The upgrade to LTE Advanced, introducing data rate

    enhancement through carrier aggregation, was first introduced in 2013. It provides a peak cell

    capacity of 1.2 Gbit/s.

    3.1 5G requirements

    In 2012, the METIS research project, one of many projects dedicated to the development of 5G

    within the EU co-funded FP7 and Horizon 2020 research programs, set out the design targets for

    5G as follows:

    1000 times higher overall capacity 10-100 times more devices

    10 to 100 times higher end-user data rates 5 times lower latency

    10 times longer battery life

    The 1000-fold capacity increase is foreseen to be achieved through 3 simultaneous approaches:

    network densification, providing 50x improvement; the use of more spectrum, including higher

    frequencies, such as mm Wave (e.g. 24 and 60-80 GHz), providing 10x improvement; and

    realising an increase in spectral efficiency, providing 2x improvement.20

    In addition to the EU research initiatives, a 5G public-private partnership, called the 5G-PPP, has

    been formed. It brings together research institutes, operators and vendors, and was endorsed

    by the European Commission. A 5G Infrastructure Association was also founded and has

    formulated a vision on 5G including (much similar) high-level requirements (5G Infrastructure

    Association, 2015).21.

    18 This Section draws on the research first reported in “Imagine 2025” published as Appendix 2 to the CERRE report

    “An integrated regulatory framework for digital networks and services” (De Streel & Larouche, 2016). 19

    In the context of LTE telephony, services are provided through Voice-over-LTE (VoLTE) or a fall-back to 3G or 2G, so-

    called Circuit Switched Fall-back (CSFB) until VoLTE is made available. 20

    This compares well with a doubling of aggregate network capacity every 3 years over the last 30 years (Rysavy

    Research, 2015). 21

    For an overview of global 5G initiatives, see the report by 4G Americas (2014a).

  • 170330_CERRE_5GReport_Final 26/116

    According to the Association 5G Vision’s statement, the 5G design is aimed at:

    • bringing together the various radio access technologies (e.g. GSM, UMTS, LTE, Wi-Fi and satellite) to provide the end-users with seamless handovers;

    • to provide a multitenant environment for various users groups (mobile operators, broadcasters, public safety and disaster relief, providers of cellular service for the

    railways); thereby

    • paving the way for virtual pan-European operators, relying on national infrastructures.

    The performance objectives formulated are:

    • radically higher wireless area capacity (1000x relative to 2010); • much lower round-trip delays (latency

  • 170330_CERRE_5GReport_Final 27/116

    Next to functional requirements related to data rates, latency, number of devices, etc. a set of

    design principles have been formulated by the Next Generation Mobile Network Alliance on

    behalf of its members. These design principles reflect the operational requirements of the

    mobile network operators (see Figure 2).

    3.2 5G architecture and virtualisation

    The overall 5G architecture as foreseen by the NGMN is reflected in Figure 3. It reflects the

    layered structure including virtualisation and the use of APIs.

    Figure 3: 5G architecture

    Source: NGMN Alliance (2015).

    The major new technological development affecting 5G is network virtualisation and the use of

    application programming interfaces (APIs). Network virtualisation refers to implementing the

    functions of the communications infrastructure in software running on commercial ‘off-the-

    shelf’ computing equipment, essentially Ethernet switches linked by optical fibers being

    centrally controlled by software. This follows the virtualisation of data centres and the use of a

    modified version of the Internet protocol adapted towards centralised network control. More

    specifically, 5G will be implemented based on software-defined networking (SDN) and network

    function virtualisation (NFV), mobile edge computing (MEC) and fog computing (FC), in essence

    an architecture based on “cloud” computing, linking together a diverse set of resources for

    transport, routing, storage and processing, including (user) resources at the edge of the

    network. Moreover, it supports the development of new services through application

    programming interfaces.22

    22 Sources: Patel et al. (2014); 5G Infrastructure Association (2015). For small scale application and experimentation

    with virtual networks see for instance the PhD by Strijkers (2014). For information on SDN in general, see Göransson

    & Black (2014) and Stallings (2016).

  • 170330_CERRE_5GReport_Final 29/116

    Virtualisation already started in the fixed network with AT&T being in the lead and Verizon a

    close follower. AT&T described the motivation to move towards network function virtualisation

    (NFV) as follows: “AT&T’s network is comprised of a large and increasing variety of proprietary

    hardware appliances. To launch a new network service often requires adding yet another

    variety, and finding the space and power to accommodate these boxes is becoming increasingly

    difficult. This difficulty is compounded by increasing costs of energy, capital investment, and

    rarity of skills necessary to design, integrate and operate increasingly complex hardware-based

    appliances. Moreover, hardware-based appliances rapidly reach end-of-life, requiring much of

    the procure-design-integrate-deploy cycle to be repeated with little or no revenue benefit.

    Additionally, hardware lifecycles are becoming shorter as technology and service innovation

    accelerates, and this can inhibit the expeditious roll out of new revenue earning network

    services and constrain innovation in an increasingly network-centric connected world. NFV aims

    to address these problems by evolving standard IT 29 virtualisation technology to consolidate

    many network equipment types onto industry standard high volume servers, switches and

    storage that can be located in data centres, network PoPs or on customer premises. This

    involves the implementation of network functions in software, called Virtual Network Functions

    (VNFs), that can run on a range of general purpose hardware, and that can be moved to, or

    instantiated in, various locations in the network as required, without the need for installation of

    new equipment.”23 AT&T senior management announced as target 75% of the network to be

    virtualised by 2020.

    The compelling reasons for applying virtualisation are: lower capital expenditures, benefiting

    from economies of scale in the IT industry; lower operating costs; faster deployment of new

    services; energy savings; and improved network efficiency.

    The European Telecommunications Standards Institute (ETSI) has standardised the framework,

    including interfaces and reference architectures for virtualisation (see Figure 4 showing the ETSI

    framework, in which virtualised network functions – VNFs – are the nodes or applications by

    which operators build services). Other standards and industry groups involved include 3GPP, The

    Open Network Foundation, OpenStack, Open Daylight, and OPNFV.24

    23 AT&T (2013).

    The core network, consisting of fewer nodes, provides an easier starting point for virtualisation.

    Although more complex, virtualisation of the RAN is expected to provide the greatest network

    efficiency gains, particularly for small-cell deployments.25

    Virtualisation and the decoupling between radio access technologies (RATs) and the core

    network (CN) functionalities support the principle of network slicing. In that way, the various 5G

    use cases with different requirements on the radio interface and in terms of data processing in

    the core network can be combined and supported by one integrated mobile network. For an

    illustration see the ‘paring’ of RATs with CN slices in Figure 5.

    3.4 The demand-side perspective

    This section provides the demand-side perspective of 5G, largely as an extension of the current

    trends.

    3.4.1 The market for connections and devices

    Figure 6 provides Cisco’s forecast for growth and penetration of global consumer mobile

    services towards 2019 (Cisco, 2015b).

  • 170330_CERRE_5GReport_Final 33/116

    Figure 6: Forecast global mobile consumer services, 2019

    Source: Cisco VNI Mobile, 2015(Cisco, 2007).

    Note that all but one of the services shown are applications which use the mobile infrastructure

    to obtain access to the Internet. Only MMS is an integrated service, which is shown with a

    negative growth rate. Moreover, mobile telephony and SMS as distinct services have

    disappeared from the radar screen, having become part of mobile social networking.

    Using Cisco’s VNI 2016 projections, the mobile communications landscape will have the

    following features by the time 5G is introduced, i.e. 2020:

    • Global mobile data traffic will increase nearly eightfold between 2015 and 2020. Mobile data traffic will grow at a compound annual growth rate (CAGR) of 53 percent from 2015

    to 2020, reaching 30.6 exabytes26 per month by 2020.

    • By 2020, there will be 1.5 mobile devices per capita. There will be 11.6 billion mobile-connected devices by 2020, including M2M modules—exceeding the world’s projected

    population at that time (7.8 billion).

    • Mobile network connection data rates will increase more than threefold by 2020. The average mobile network connection speed (2.0 Mbit/s in 2015) will reach nearly 6.5

    Mbit/s by 2020.

    • By 2020, 4G will represent 40.5 percent of connections and 72 percent of total traffic. By 2020, a 4G connection will generate 3.3 times more traffic on average than a non-4G

    connection.

    • By 2020, more than 60 percent of all devices connected to the mobile network will be “smart” devices. The vast majority of mobile data traffic (98 percent) will originate from

    these smart devices by 2020, up from 89 percent in 2015.

    • By 2020, 66 percent of all global mobile devices will be capable of connecting to an IPv6 mobile network. There will be 7.6 billion Ipv6-capable devices by 2020.

    26 Exabytes: 1 EB = 1000

    6 bytes = 10

    18 bytes = 1000 petabytes = 1million terabytes = 1billion gigabytes.

  • 170330_CERRE_5GReport_Final 34/116

    • By 2020, 75 percent of the world’s mobile data traffic will be video. Mobile video will increase 11-fold between 2015 and 2020.

    • The amount of mobile data traffic generated by tablets by 2020 (2.6 exabytes per month) will be 7.6 times higher than in 2015, a CAGR of 50 percent.

    • The average smartphone will generate 4.4 GB of traffic per month by 2020, nearly a fivefold increase over the 2015 average of 929 MB per month. By 2020, aggregate

    smartphone traffic will be 8.8 times greater than it is today, with a CAGR of 54 percent.

    • Currently, more than half of all traffic from mobile-connected devices (almost 3.9 exabytes) is offloaded to the fixed network by means of Wi-Fi devices and femtocells

    each month. Without Wi-Fi and femtocell offload, total mobile data traffic would grow

    at a CAGR of 55 percent between 2015 and 2020, instead of the projected CAGR of 53

    percent.

    • The Middle East and Africa will have the strongest mobile data traffic growth of any region with a 71-percent CAGR. This region will be followed by Asia Pacific at 54 percent

    and Central and Eastern Europe at 52 percent.

    See also Figure 8 for the projected mobile traffic growth.

    Eastern Europe for 14%.

    3.4.2 The IoT market

    Following the major transition from car-borne phones to handsets, the next major expansion of

    the addressable market is the Internet-of-Things (IoT), or the interconnection of uniquely

    identifiable embedded computing-like devices using the Internet. IoT requires: (1) the transition

    27 LPWA: Low power wireless access, mainly used for connections in the context of IoT.

  • 170330_CERRE_5GReport_Final 36/116

    to IPv6, which has a much larger address space of up to 3.4×1038; (2) high as well as very low

    data rates; and (3) very low energy consumption.

    IoT includes the earlier form of machine-to-machine (M2M) communication, which originated in

    the field of industrial instrumentation. The ubiquitous use of the Internet facilitates M2M

    communication and expands its range of applications. Previously, this was also denoted as

    telematics. Meanwhile, many mobile operators have created business departments dedicated to

    providing M2M services. As an example, a number of energy utility companies have outsourced

    the collection of smart-meter data to communication providers. At least one of the utility

    companies has acquired a radio spectrum license to set up a network to collect metering data

    over the air.28

    The lowest-cost devices enabling M2M communications today are GPRS modems, which may

    become obsolete as operators decommission their GSM systems. HSPA is also used for M2M

    communications. Furthermore, LTE has been optimised to efficiently communicate small bursts

    of information, making it well suited for M2M. Low-cost LTE modem options included in 3GPP

    releases 10 through 13, reduced costs, improved the communications range, and extended

    battery life (Rysavy Research, 2015). Figure 9 reflects the forecasted use of mobile technologies

    for M2M.

    Figure 9: Global mobile M2M connections by technology, 2015-2020

    Source: Cisco VNI Mobile, 2016.

    5G is set to serve the two different segments of the IoT market: (1) the market of massive

    machine-type communications (mMTC), related to smart cities, smart infrastructures and

    objects (sensors and actuators); and (2) the market for ultra-reliable and low-latency machine-

    type communication (uMTC), related to autonomous vehicle control, smart electricity grids and

    factory cell automation.29

    IoT is considered to include a very wide range of applications such as: environmental

    monitoring; energy management; remote health monitoring and notification; building and home

    automation; smart vehicles; and more. Contributing to the growing adoption of Internet-of-

    Everything (IoE) are wearable devices. Wearable devices have the capability to connect and

    communicate to the network either directly through embedded cellular connectivity or through

    another device (primarily a smartphone) using Wi-Fi, Bluetooth, or another technology. These

    devices come in various shapes and forms, ranging from smart watches, smart glasses, heads-up

    displays (HUDs), health and fitness trackers, health monitors, wearable scanners and navigation

    devices, smart clothing, etc. The growth in these devices has been fuelled by enhancements in

    technology making the devices light enough to be worn. These advances are being combined

    with fashion to match personal styles, especially in the consumer electronics segment, along

    with network improvements and the growth of applications, such as location-based services and

    augmented reality.30

    According to Cisco´s 2015 VNI projection, M2M connections will grow to over 10 billion

    worldwide by 2019, with 4.6 Petabytes of traffic per month. See Figure 10 for the growth rates

    and a breakdown by industry vertical (Cisco, 2015a). In the 2016 outlook, the forecast is lowered

    significantly based on a lower take up in the early years: globally, M2M connections will grow

    from 604 million in 2015 to 3.1 billion by 2020, a 38-percent CAGR.

    4 The two stylised images of the 5G future

    It has been said that ‘forecasting the future is best done in hindsight’. Nonetheless, exploring

    what the future might bring remains of critical importance in successfully managing a business.

    As the policy enterprise has in common with the business enterprise the need to explore the

    future to devise successful policies, we present two contrasting stylised images for the 2020-

    2025 horizon. These two images represent two extremes to capture the widest range of possible

    5G futures. These images of the future neither aim at representing the complexity of how the

    actual future may unfold, nor should be considered as scenarios, such as those initiated by Shell

    in the eighties.

    To avoid any doubt on the purpose of the images, we are not suggesting that either one of these

    represents the most likely future outcome. The future may evolve as a mixture of these two in a

    pattern which varies over time and place, or may be different from what is described. The two

    images have been developed to highlight the range of 5G challenges which are likely to be faced,

    and thus focus attention on the key short and medium term choices concerning policy and

    regulation which have to be made to assure the successful development and deployment of 5G

    in Europe.

    4.1 ‘Evolution’ and ‘Revolution’

    The stylised images are called ‘Evolution’ and ‘Revolution’. They represent respectively a

    continuation of the development path of mobile communications as it can be derived from the

    development of the previous generations, i.e. 1G through 4G, and a break with past

    developments made possible through technological developments, i.e. the virtualisation of

    communications networking. The contrast between the images is in the two different industry

    structures they represent. On the one hand, the continuation of an oligopolistic market

    structure of incumbent mobile network and service providers, and on the other a market that is

    driven by a wide range of firms specialised in serving the requirements of different (vertical)

    industries through applications running on open access network infrastructures, providing

    seamless service on a regional basis.

    The two images are informed by research into, on the one hand, the development of 1G through

    4G – in particular an investigation into regularities and trends that can be observed – and on the

    other hand, the relatively recent experience with the development and deployment of

    virtualisation in data centres and the steps taken by AT&T and Verizon to virtualise their telecom

    infrastructures.

  • 170330_CERRE_5GReport_Final 39/116

    4.2 The industry structure

    To describe the 5G communication services industry structure and environment under the two

    stylised images, use is made of the framing provided by Porter and Wheelen, i.e. a combination

    of the Five Forces framework and the SEPT framework respectively, to which the environmental

    dimension is added31 (see Figure 11).

    Figure 11: Framework for industry analysis (Porter-Wheelen)

    Source: Author, based on Porter (1980) and Wheelen & Hunger (1983).

    The SEPT dimensions provide a sketch of the broader socio-economic context in which the more

    detailed ‘Evolution’ and ‘Revolution’ images are positioned.

    31 It is acknowledged that the Porter framework provides a static view of the industry and needs to be used in a

    comparative static mode to capture dynamic aspects. In the context of the image development its main purpose is to

    structure the information and act as a check to assure all relevant dimensions are addressed. Sources: Porter (1980)

    and Wheelen & Hunger (1983).

    5 The ‘Evolution’ image

    In the ‘Evolution’ image? the regularities and trends that can be observed from the previous

    generations of mobile communication, i.e. 1G through 4G, are considered as the main

    determinants of the 5G future. The incumbent operators consider spectrum holdings, the active

    parts of the network and customer relationships as their core strategic assets – while passive

    infrastructure (e.g. towers) are sold and leased back, and maintenance is increasingly

    outsourced to third parties. It provides opportunities for vertical integration of networks and

    services and thereby differentiation from the so-called Over-the-Top service providers. The

    incumbent operators deploy new technologies to defend and strengthen their position vis-à-vis

    the competitors and in developing the relationship with their customers. A key assumption in

    this image is that the core business of the mobile operators continues to be serving the mass

    market of consumers.

    5.1 Anticipated outcome – attractiveness of the outcome32

    This section describes the anticipated outcome of the future image in hindsight.

    In the ‘Evolution’ image – described in Section 5.2 – the leading players are the incumbent

    mobile operators. Given the competitive market place and consumers having become used to

    getting access to more bandwidth with each new generation at roughly the same price, the

    profit margins remain small. Hence, the incumbents have a strong incentive to optimise past

    investments and to be prudent with new investments. The business case has become more

    challenging with each new generation, as the investment costs per subscriber increased while

    per subscriber revenues remained flat. See Figure 12.33

    32 In this Section we compare the outcome of the image of the 5G future with the GSM success factors derived in

    Section 2. 33

    LTE being a high-capacity All-IP system removed past infrastructure bottlenecks and provided a

    controlled path towards the future, with the introduction of LTE-Advanced, as well as upgrades

    of functionality through annual releases. With the relative low and stable prices paid by end-

    users, largely irrespective of the increase in data rates offered, this evolutionary image fits the

    desire for a stable business model with relatively flat investment levels.34 This provides for

    relatively stable and predictable performance.

    As the 5G architecture evolved by adding new radio interfaces in bands above 24 GHz to the

    existing LTE core network, incumbents can serve the demand for higher data rates in an

    incremental way, particular in high density city areas, as and when demand is manifest. The

    replacement of the LTE core network by a 5G core network could be phased, based on new

    products becoming stable and being provided at lower costs.

    As the newly available frequency band below 1 GHz, i.e. the 700 MHz band, was already

    auctioned for use by LTE and LTE-Advanced, there was no direct linkage between the release of

    this new spectrum and the introduction of the new 5G technology. The introduction of spectrum

    bands above 24 GHz was, and still is, of importance for network densification to provide higher

    data rates. However, this did not provide a window of opportunity for infrastructure market

    entry as part of 5G. Hence, increased competition as a major driver of success related to GSM

    was lacking in the context of 5G.

    The market of IoT provided opportunities for growth, but this market is highly diverse and

    served by competing technologies operating in unlicensed bands, such as LoRa. These

    34 The investment profile typically reflects investments in coverage in the early period and investments in capacity

    upgrades (densification) in the subsequent period.

    alternative technologies were designed for IoT from the outset, with long range and low power

    as design objectives. These systems appeared to be more effective than scaled-down versions of

    high-capacity cellular systems. Hence, they provide effec
